BSOD after a while playing eve online + browser

Hey guys.
I play Eve online with 3 accounts and they are most of the time online in the Background. While that i do different things in browser. Playing eve with 3 instances as the same time is normal for this game, nothing Special.

It started a while ago, if i do a lot in browser Tabs (Chrome or opera) i got BSOD with different types. Sometimes after 1h, most of the times sites crashed (1 tab = single Windows process). Now over Christmas i cleaned everything, new Windows Image, new Drivers etc. I hoped it is better.

then i got a BSOD Memory corruption also after a while (first dump was after 30min, second one after 3h).



EDIT:
I kicked out avira and the 2x4gb ram, use my old 2x8gb. I did the same and it took some hours but i got a Crash again, but ist different. Can you tell me whats that last one in the second file from 28.12.? I think the last one is interessting. the one before occurs when i changed RAM etc. There was a bluescreen on a normal shutdown.


thanks and best regards

Try removing the 4GB module then run for awhile, see if that resolves the problem. Sometimes it does, sometimes not. If it does, replace the 4GB module3 with one identical to teh 8GB you have or leave the 4GB out.

The older dump indicates a problem with AVG:

Code:

BugCheck 1A, {4477, 1fffffd0, 0, 0}
*** WARNING: Unable to verify timestamp for avgntflt.sys
*** ERROR: Module load completed but symbols could not be loaded for avgntflt.sys

Uninstall AVG anti-virus.
Make sure Windows Defender and Windows Firewall are enabled.

Run that way for awhile to test, see if that resolves the problem.
